Water Cooled Screw Chiller Efficient Operation
- Nov 03, 2017 -

Water-cooled semi-enclosed screw chiller is a water-cooled central air conditioning products, compared with the same cooling capacity of the air-cooled units, because of its condenser and evaporator are made of highly efficient heat transfer tube production and therefore compact , Small size, high efficiency; and because there is no condenser fan, so the noise is low.

In the water-cooled semi-enclosed screw chiller manufacturing has a mature technology, Water Cooled Screw Chiller sound technology and advanced testing equipment, Water Cooled Screw Chiller coupled with a selection of world-class accessories to ensure the unit's stable and efficient operation.

Water-cooled semi-closed screw chillers can not only provide cold water to the central air-conditioning systems of hotels, hospitals, pharmaceutical plants, theaters, Water Cooled Screw Chiller stadiums, entertainment centers, commercial buildings, industrial and mining enterprises, but also for the textile, chemical, food, electronics, research Other departments such as the provision of frozen technology.

1, the unit should have a dedicated room, and should take measures to run the unit heat generated from the engine room drain away, ventilation to maintain room temperature does not exceed 35 ℃ requirements.

2, the unit should be installed on a rigid base or not deformed concrete foundation, Water Cooled Screw Chiller the foundation should be flat, should be able to withstand the weight of the unit running.

3, Drains, such as drains, should be drained around the foundation of the unit so as to discharge the water from the system during seasonal shutdown or maintenance.

4, the engine room should have enough space for the installation and maintenance of the unit; room should have enough extubation space; at the same time should not be laying pipelines and pipe above the compressor.

5, it is recommended to install the water pipe and the unit take over the size of the installation of isolation rubber bearing spacing, so that the crew arrived at the scene after the appropriate construction and adjustment space.

6, for the normal operation of electrical components, Water Cooled Screw Chiller do not place the unit in the dust dirt, corrosive fumes and humidity in large places, if any such situation exists, must be corrected.

7, should be prepared materials and tools: soft joints, shock cushion, lifting equipment, hoisting beams, hanging chain, jack, sliding pad wood, pad roll, pry bar.

1, chilled water pipeline system must be installed shockproof soft joints, thermometers, pressure gauges, water filters, electronic descaling instrument, check valve, Water Cooled Screw Chiller the target flow controller, exhaust valve, drain valve, globe valve, expansion tank.

2, expansion tank should be installed at a height of 1 to 1.5 meters above the system, (you can also use floor-based constant pressure water supply device). The tank capacity is about 1/10 of the total system water.

3, equipped with a drainage tube in the evaporator, Water Cooled Screw Chiller exhaust connector. A 1/2 "drain bronze ball valve has been fitted to the drain and the vent is sealed with a plug. Replace the screw plug with a 1 / 4NPT deflation ball valve.

4, the water pipe should try to avoid the vertical changes in the pipeline between the height and the expansion tank installed manual or automatic exhaust valve.

5, inlet and outlet pipe straight pipe install thermometer and pressure gauge, Water Cooled Screw Chiller to avoid installing it too close to the elbow. Each low point should be equipped with a water connection to clear the system of excess water. Before operating the unit, connect the stop valve to the drain pipe and install it near the inlet and outlet connections. Evaporator pipe should be between the bypass pipe, Water Cooled Screw Chiller easy to pipe cleaning and maintenance. Use flexible joints to reduce vibration transmission.

6, frozen water pipes and expansion tank should be heat treatment, valve fittings should be left at the maintenance operation site.
